NVIDIA has done pretty well on the mobile market with its Tegra 3 processor, and it should be of no surprise to anyone that NVIDIA has been working on the next generation Tegra processor. The company even provided some rough details early last year.

However, some detailed information on the next-generation 28nm Tegra 4 leaked today, and it promises six times the power of Tegra 3. Tegra 4 appears to be, according to a leaked slide, a 4+1 quad-core design similar to that of the current Tegra 3. The Cortex-A15-based Tegra 4 has 72 graphics cores and supports dual channel memory. Tegra 4 will also support resolutions of 2560 x 1440 for encode and decode and promises very low power consumption.

Other supported features will include the USB 3.0, making this the first NVIDIA chipset to support the new and faster USB standard.

With CES 2013 kicking off in mere weeks, we should have significantly more details coming in the not-too-distant future.

Many tasks? I can't think of much besides surfing the web. Games tend to suck on mobile, programming or anything above basic text editing is a no-go.Sure, people use tablets, but I have yet to see anyone giving up on their PC/laptop in favour of a tablet.

In my job I need the quad core, 16 GB memory 27" screen, terabyte of local hard disk and mechanical keyboard to do my work. Without them i would be castrated.

Since I am getting all that on a laptop (screen via docking station), I can carry it with me too.

As for OS, serously? I multitask like a madman. i NEED to have 5-15 windows open on my deskop so I can monitor what is going on in most of them at once. Even with Android 4.2 I cant do that with 'multiwin' - the screen real estate just is not there. And Windows 8 RE... forget that crap.

The whole big screen phone / tablet / multi tasking thing is a white elephant and harks back to why tablets were a failure up to a couple of years ago and still nerds bang on that they need to have massive, bloated feature sets.

There is no substitute for a desktop for some work situations, even some that can't be achieved with quite the same efficiency on a laptop. Forget mobile OSs, no matter how much they cram into them it will just make them inefficient at what tablets are best at. It will never make them anything close to a desktop / laptop replacement.
